1 INTRODUCTION

Hydro's Circuit Breaker Upgrading project is required to refurbish or replace circuit breakers.

The majority of circuit breakers have been in service for more than 30 years. As they age, the

risk of failure increases.

Hydro has 182 circuit breakers rated for voltages at 66 kv and above. Figure 1 provides the age

distribution of all breakers by voltage class.

Circuit Breakers serve a critical function to the power system and are placed in terminal stations

to perform switching actions to complete, maintain, and interrupt current flow under normal or

fault conditions. Fast response and complet e interruption are essential to protect the rest of

the power system from a faulted component and maintain the stability of the system.

Currently, Hydro maintains t hree different types of circuit breakers at 66 kV and above: Air

Blast Circuit Breakers, Oil Circuit Breakers (OCB) and Sulphur Hexafluoride (SF6) Circuit

Breakers. SF6 breakers are the newest design and are currently the only option for

replacement for applications 66 kV and above.

Newfoundland and Labrador Hydro 1



Each type of circuit breaker has unique operating characteristics. Air blast circuit breakers offer

features such as fast response and automatic reclosing. They are widely used where repeated

operation is essential. Unlike air blast breakers, which extinguish the arc using air as medium,

oil circuit breakers extinguish the arc using insulating oil. SF6 circuit breakers use SF6 gas

because of its highly reliable dielectric characteristics for arc extinguishing. The trend in the

utility industry is towards SF6 breakers because of the superiority of the new technology and its

operating characteristics.

Figure 2: Circuit Breakers {Air Blast, Oil, and SFG; from left to right)

The basic components of a circuit breaker are the interrupting device (stationary contact,

moving contact, arc quenching medium and insulating material) and the operating mechanism.

With air blast circuit breakers, both the interrupting device and operating mechani.sm require a

mid-life overhaul of seals, 0-rings, and lubrication. Oil circuit breakers require oil maintenance

and possibly contact replacement, while SF6 breakers will typically only require an operating

mechanism overhaul at mid-life as the interrupter is a sealed unit. However, for new high

voltage circuit breakers, the only replacement option available on the market today is SF6

circuit breakers.

Oil circuit breakers will be replaced and not refurbished due to a legislative requirement to

remove Polychlorinated Biphenyls {PCBs) which are contained in the OCB bushings.




2 PROJECT DESCRIPTION

With circuit breakers being a critical and a high-cost capital asset, Hydro, like many North

American utilities, has been working to maximize the life of its service units. In recent years,

Hydro has been upgrading air blast circuit breakers, overhauling operating mechanisms

associated with SFG breakers, and attempting to deal with the phase out of bushings containing

polychlorinated byphenols (PCBs), such as those associated with OCBs This project will address

all three critical areas with the following criteria being adopted for each circuit breaker type.

2.1 Air Blast Circuit Breakers

Complete one overhaul on air blast circuit breakers through the breaker life and replace air

blast circuit breakers after approaching at least 50 years of service and 10 and 15 years after

overhaul. Depending upon breaker reliability, air blast breakers will be considered for

replacement at the age of 50 years.

To help balance financial and human resources over time, exceptions to the above criteria will

include:

A. The Asea Brown Boveri (ABB) type DLF1 breakers will have one breaker replaced at the age of

40 to facilitate the overhaul of remaining DLF type breakers. The parts from this breaker will

be sent to the original equipment manufacturer (OEM), ABB, for overhaul and then installed

on another breaker and the latter's parts will be shipped to the OEM for overhaul. This

process will continue for the duration of the overhaul program which is currently planned to

have three DLF type breakers overhauled per year starting in 2013, and continuing until

2019.

1 DLF is a type number for breakers assigned by the manufacturer.




B. Breakers will also be replaced if terminal stations are upgraded. The same is true for any

circuit breaker upgrades required for the future development of the Labrador infeed.

C. Breakers will also be considered for replacement if their components have deteriorated such

that it warrants replacement.

2.2 Oil Circuit Breakers

An oil circuit breaker will be scheduled for replacement prior to 2025. The existing oil circuit

breakers have sealed bushings which potentially contain polychlorinated phenyls greater than

500 mg/kg.

2.3 SF6 Breakers

Complete one overhaul after 20 years for all new SF6 breakers and complete an overhaul

between 20-30 years for existing in-service units. This approach was taken for existing units in

service to help balance the financial and human resources, and to minimize outages to the

power system. The plan for routine replacement will be after 40 years of service. Other

breakers will be given consideration for replacement based upon their condition and

operational history. For example, Hydro has replaced air operated SF6 breakers in recent years

due to gas leaks, problems with the operating mechanism and corrosion of air receiver tanks.

One 69 kV SF6 breaker was replaced in Howley in 2009 and one SF6 breaker was replaced in St.

Anthony in 2011 and another at St. Anthony is scheduled to be replaced 2012. Also, one 138 kV

SF6 breaker was replaced in Bottom Brook in 2010.

The main objective for this project is to take an overall strategic approach for all existing circuit

breakers. This approach supports the corporate asset management philosophy, complies with

current legislation and minimizes customer outages.




It is important to note some items not included in the methodology of this plan are:

1. There are no 66 kV voltage class air blast circuit breakers included in this proposal; and

2. There will be no overhauls on 66 kV voltage class SF6 circuit breakers as replacement is

more cost effective. These replacements will occur typically 40 years after being in

service. The actual timing of replacement will be determined based on breaker

condition.




3 JUSTIFICATION

As illustrated in Figure 1 of this report, 62 percent of Hydro's circuit breakers are greater than

30 years of age and 47 percent are greater than 35 years of age. In recent years, Hydro has

been trying to address breaker overhauls and replacements through separate capital budget

proposals. With an effort to bring a consistent and consolidated long term asset plan forward

for circuit breakers it was decided to develop a plan for circuit breakers which will cover the

following:

• Air blast Circuit Breaker Overhauls of DCF, DCVF and DLF breakers;

• SFG Operating Mechanism Overhauls;

• Oil Circuit Breaker replacements to replace aging assets and comply with legislation

(deal with possible PCB bushings);

• SFG Breaker Replacements; and

• Air blast Circuit Breaker Replacements.

To maintain the reliability of in-service breakers, Hydro plans to address its aging circuit

breakers. To help balance financial impacts and system outage constraints, Hydro has

developed a circuit breaker long term asset management plan that will have air blast circuit

breaker overhauled and their lives extended to at least 50 years, SFG breakers overhauled to

maintain a life of 40 years, and oil circuit breakers replaced to ensure compliance with PCB

regulations.




3.1 Existing System

This project is required to overhaul or replace aging circuit breakers in service for Hydro.

Figure 3 shows the age distribution for Hydro's circuit breakers rated 66 kV and greater. These

demographics highlight the following that will affect the future management of circuit breakers:

1. The average age of the overa ll population of circuit breakers is well past a breaker's midlife of

20 years and is fast approaching the manufacturers' specified design end-of-life of 40 years.

2. 61 breakers are already greater than 40 years of age.

3. In order to keep the age of these breakers below 40 years, 61 breakers would require

immediate replacement with an additional five breakers being replaced annually. This

approach would result in a significant cost and as a result an alternate plan for rehabilitation

was considered.

4. With reliability not being a concern for Hydro's air blast circuit breaker fleet, Hydro feels air

blast breakers life can be extended 10 to 15 years after overhaul and at least to the age of 50

years. SF6 breakers will be replaced after 40 years of service and all oil circuit breakers will

be replaced by 2025 because of PCB contamination.

In the past ten years there have been overhauls completed on air blast circuit breakers and the

operating mechanism associated with selected SF6 Breakers. See Appendix D showing all

overhauls completed prior to 2012.

3.1.1 Air Blast Circuit Breaker Overhauls

Since 1999, overhauls have been completed on air blast circuit breakers. By the end of 2012, it

is expected, 40 of 66 breakers will have been overhauled. The current proposal will provide the

funding to continue with this program to complete the remaining overhauls to extend breaker

life from 40 to at least SO years.

This project wil l also be the source for funding replacements of air blast breakers as they reach

between 10 and 1S years past overhaul and an age of SO years or greater. See Appendix A for

the multi-year overhaul and replacement plans.

Figure 4: Air Blast Circuit Breaker during an Overhaul

3.1.2 SF6 Breaker Overhauls

In 2004, Hydro adopted a philosophy of overhauling operating mechanisms associated with 230

kV and 138 kV SF6 breakers. By the end of 2012 there will be 20 breakers overhauled. The plan

is to complete three to four overhauls per year for a total of 37 by the end of 2017. See

Appendix B for a list of SF6 breakers showing the next planned overhaul date and the planned

replacement date.




Figure 5: SFG Breaker during an Overhaul

3.1.3 Oil Circuit Breakers

There has been no major overhaul work performed with OCBs. Hydro plans to replace all OCBs

by 2025 to ensure Hydro is compliant with the latest PCB regulations. Appendix C outlines the

replacement plan for OCBs. Typica lly, older breakers will be replaced first. However, the

replacement plan is prioritized in the early years to first remove from service breakers with

known problems such as high contact resistance or poor Doble power factor readings.

3.2 Anticipated Useful Life

With the current age of the existing circuit breaker fleet the lack of availability and failure of

circuit breakers can be expected if refurbishment or replacement activities are not commenced.

Hydro has been legislated to meet PCB Regulation targets for equipment containing PCBs such

as bushings in OCBs. The status quo for 66 kV, 138 kV and 230 kV voltage class circuit breakers

is not an option.




3.3 Maintenance History

For the purpose of determining how well an asset is performing Hydro will compare a particular

asset against the national average of performance for that asset. This national average is based

on a combination of data collected by the Canadian Electricity Association (CEA) which includes:

forced outages, frequency of failure, and the availability of the asset. Table llists the

performance data for each criterion. The listed data is the performance averages for Hydro's

circuit breaker asset over the previous five-years for 138 kV and 230 kV circuit breakers in

comparison to the national average of 138 kV and 230 kV circuit breakers. The comparison uses

the performance data from the latest CEA five year average data collected between 2006

through 2010.

3.4 Outage Statistics

From Table 1 below it should be noted that Hydro experienced 22 forced outages due to

problems with these breakers over the last five years.

3.4.1 Legislative or Regulatory Requirements

The use of PCB material in oil circuit breaker bushings has presented an environmental issue

which has led to the development of a plan for its removal and safe disposal. Prior to the mid

1980s the manufacturers of bushings used insulating oil containing PCBs with concentration




varying from less than 2mg/kg to greater than SOOmg/kg. The latest federal PCB Regulations

(SOR/2008-273) provided an end of use date for different concentrations of PCBs. Section 16(1)

states that the end of use for equipment containing PCBs in a concentration of SOO mg/kg or

more was December 31, 2009; and for equipment containing PCBs in a concentration of at least

SO mg/kg but less than SOO mg/kg is December 31, 202S. The regulations also gave utilities an

option to apply for an extension until 2014 to have all equipment containing greater than SOO

mg/kg removed. Hydro, like other Canadian Electricity Association (CEA) members, has a

significant amount of sealed equipment with unknown levels of PCBs. As a result, Hydro applied

for and in 2010, was granted an extension until December 31, 2014.

Due to the large volume of equipment containing PCBs with varying and unknown levels of PCB

concentration, CEA members including Hydro are actively pursuing a regulatory amendment to

allow the use of bushings and instrument transformers with PCB concentrations of SOO mg/kg

and greater until December 202S. This application presents a plan to meet a 202S deadline, not

a 2014 deadline. If this regulatory amendment is not granted, the capital investment required

for oil circuit breaker replacements will have to increase significantly for 2014.

3.5 Industry Experience

Many utilities in North America are in a similar position as Hydro in that they have aging

infrastructure and are seeking the most economic and reliable solution to refurbish and replace

circuit breakers.

3.6 Vendor Recommendations

ABB, the OEM for the Air Blast Breakers, indicate that overhauling the units will extend the life

of the unit for approximately 1S years. This will allow air blast breakers to have an anticipated

useful life of at least SO years. As result of this, Hydro plans to overhaul the remaining air blast

circuit breakers and schedule their replacement 10 to 1S years after the overhaul and upon

reaching an age of SO years.




The majority of the vendors for 138 kV and 230 kV SFG breakers suggest the breakers are

suitable for 40 years of operation provided an overhaul is completed near the mid life of the

circuit breaker. Hydro has taken the approach to do this mid-life overhaul in a planned

approach to minimize cost and outages to the system. The current plan is to overhaul three to

four circuit breakers per year until 2017. Beyond 2017, overhauls will be planned after the

breaker has been in service for 20 years.

3. 7 Maintenance or Support Arrangements

For air blast circuit breaker overhauls, Hydro uses a common supplier for all for all overhaul

parts associated with DCF type and DCVF type air blast breakers, and Hydro staff complete

overhauls. This approach will continue for remaining DCF/DCVF type circuit breakers.

With respect to SFG overhauls, Hydro has used ABB to assist with the overhaul of the ABB 230

kV ELF breakers and Siemens Canada Ltd. to direct the work associated with the overhaul of

Siemens 230 kV 3AQ1 breakers.

The plan for the overhauls associated with DLF air blast circuit breakers, and 138 kV and 230 kV

SF6 breakers will also be to partner with the OEM.

3.8 Maintenance History

For air blast breakers, Hydro has experienced problems with air leaks and valves sticking,

resulting in increased maintenance costs and breaker unavailability. Such problems have

mainly been a result of seals and 0-rings deteriorating over time. The problems experienced by

Hydro are common in the utility industry and owners of these types of air blast breakers have

addressed the problem through similar upgrading programs. For example, Hydro One has

chosen to complete a mid-life overhaul of their air blast circuit breakers after 20 to 25 years of

service and are now considering the units for replacement after 40 to 50 years of service.




The two main problems experienced with SF6 breakers have been gas leaks and operating

mechanism malfunctions. Breaker B3LSO at Bottom Brook was replaced in 2010 due to gas

leaks that were reoccurring and could not be repaired. Breaker LS1T2 at Howley was replaced

in 2009 due to severe corrosion of the receiver associated with the breaker.

With OCBs, the main problems experienced have been high contact resistance and poor oil

condition. Both these factors are considered in prioritizing breakers for replacement.

The five-year maintenance history for circuit breakers is shown in Table 2.

Table 2: Five-Year Circuit Breaker Maintenance History Preventive Corrective Total

Maintenance Maintenance Maintenance Year ($000) ($000) ($000)

2011 61.8 160.3 222.1

2010 50.3 64.5 114.8

2009 15.0 46.0 61.0

2008 16.4 116.0 132.4

2007 7.7 121.0 128.7

3.9 Anticipated Useful Life

Circuit breakers are depreciated over a 55 year period. For replacement, 40 years will be the

trigger point for SF6 type circuit breakers, while air blast circuit breakers will typically be

replaced 10 to 15 years after overhaul and after the breaker reaches the age of 50 years.

Overhauls in the past 10 years have proven effective in maintaining the reliability of ABCBs and

extending their lifecycle.

3.9.1 Development of Alternatives

The purpose of this project is to provide 66 kV, 138 kV and 230 kV circuit breakers that are

reliable, cost effective, and are more environmental friendly. The three possible alternatives to




achieve this goal are:

1. Replacement of all circuit breakers at the age of 40 years;

2. Refurbishment of failed circuit breakers as they occur; and

3. Replacement and refurbishment of circuit breakers in a planned strategic approach to

balance financial and human resources and minimize outages.

3.9.2 Evaluation of Alternatives

1. Replacement of all circuit breakers at the age of 40 years: This alternative will require 61

breakers to be replaced immediately which will result in significant cost and will require

outages to the system that will not be possible. As a result this alternative will not be

pursued.

2. Refurbish failed circuit breakers as they occur: This is a run-to-failure approach and this

philosophy is not prudent to maintain system reliability. A planned approach is required

to ensure circuit breakers are overhauled or replaced at the appropriate time. Hydro

does not plan to pursue this alternative.

3. Replacement and refurbishment of circuit breakers in a planned strategic approach to

balance financial and human resources and outages to the power system:

In reviewing further Alternative 3, the only options to consider are overhaul versus replacement

for air blast or SFG breakers. The cost to overhaul a 230 kV air blast breaker is approximately

one quarter the cost of replacement (estimated replacement of $422,000}, one week outage

for an overhaul versus up to five weeks for replacements, and Hydro has seen high reliability

from air blast breakers particularly those with high frequency of operations, such as generating

unit breakers.

Overhauls for SFG breakers are required to restore seals and wearing parts in the operating

mechanism to achieve the service life expectation of 40 years. The cost to overhaul a 230 kV

SFG breaker is one seventh the cost of replacement (and one third the cost of replacing a 138




kV breaker.) The system outage requirement for an overhaul is typically one week versus a four

to five week outage for replacement.

It is not cost effective to refurbish 66 kV voltage class SF6 circuit breakers. Hydro has not

considered any 66 kV air blast circuit breakers in this report. Due to PCB regulations all oil

circuit breakers must be replaced instead of being refurbished.

As a result, Hydro will be pursuing Alternative 3 and using a two tiered approach involving both

overhauls and replacements to help minimize system outages and take a more balanced

financial and human resource approach.




4 CONCLUSION

Hydro plans to use a combination of overhauls and replacement for both Air Blast and SF6

breakers. The plan will see all current in-service air blast breakers replaced by 2031, all current

in-service SF6 breakers overhauled at mid life and replaced at or near age 40, and all Oil Circuit

Breakers replaced by 2023.

For air blast circuit breakers, there will be four to five overhauls completed per year. One

breaker replacement will be completed in 2012 and three replacements per year for the next

seven years. Further replacements will be required as outlined in the summary by replacement

year outlined in Appendix E.

For SF6 breakers, there will be three to four overhauls completed per year and breaker

replacements are not scheduled to begin until 2019 unless a breakers condition warrants

replacement earlier. It should be noted, there are SF6 breakers identified in the Summary by

Replacement year in Appendix E which have been approved on previous capital budget

submissions.

For Oil Circuit breakers, there are three replacements scheduled per year starting in 2012 with

the last OCB being replaced in 2023.

Table 3 summarizes the work plan for circuit breaker upgrading planned for the next five years

and Hydro is requesting approval for the first five years of its multi-year plan with this

submission.
